In addition, thoseof ordinary skill in the art will appreciate that communications amongdifferent devices of the communication system 100 are implemented viainterfaces.

The remote terminal device 110 may perform data transmission through therelay terminal device 120. For example, when receives downlink data forthe remote terminal device 110, the access network device 130 may send apaging message to the remote terminal device 110 through the relayterminal device 120. In the embodiments of the disclosure, the remoteterminal device 110 includes, but not limited to, a wearable device, asmart refrigerator, and a smart air conditioner. For example, thewearable device may include a smart bracelet, a smart helmet and thelike.

The relay terminal device 120 may establish a user plane connection withthe access network device 130 through a bearer, and may also establish acommunication signaling connection with the CP 140 through an interface.It should be understood that the relay terminal device 120 maycommunicate with multiple remote terminal devices 110.

The access network device 130 may be a device that communicates with therelay terminal device 120, such as a base station or a base stationcontroller. However, it will be appreciated that the access networkdevice 130 may communicate with any number of terminal devices similarto the relay terminal device 120. The access network device 130 may alsocommunicate with the CP 140 via an interface.

Each access network device may providecommunication coverage for a specific geographic area and maycommunicate with terminal devices (for example, UE) located within thecoverage area (cell). The access network device may support differentschemes of communication protocols, or different communication modes. Inat least one embodiment, the access network device 130 may provide awireless access service for a terminal device. For example, the accessnetwork device 130 may be an Evolved Node B (eNodeB) or a WirelessFidelity Access Point (WiFi AP), or a Worldwide Interoperability forMicrowave Access Base Station (WiMAX BS), or a controller in a CloudRadio Access Network (CRAN), or a network device in the future 5Gnetwork or a network device in the future evolved PLMN.

The CP 140 is responsible for the mobility management and forwardingpath management in the communication system 100, such as issuing apacket forwarding policy to the UP 150, or instructing a Gateway UserPlane (GW-U) to perform processing and forwarding of packet according tothe packet forwarding policy.

The session management network element is responsible forsession management of the terminal device, such as sessionestablishment, modification, or release of the session. In addition, thedecoupling implemented by control and forwarding through a gatewaydevice greatly simplifies the design of a hardware platform, reduces thecost of the hardware platform, and facilitates acceleration of thedeployment of mobile packet data networks. The MME is mainly responsiblefor mobility management and session management of a control plane, suchas user authentication, handover, mobility management of terminals inidle state, user context management, and bearer management.

The UP 150 is responsible for processing and forwarding of packet. TheUP 150 may be a physical or virtual forwarding device such as aforwarding plane function of a P-GW, a forwarding plane function of anS-GW, a router or a switch.

A terminal device, comprising: a processor, a memory for storing instructions executable by the processor, and a transceiver, wherein the processor is configured to execute the instructions to control the transceiver to: receive an instruction message from a network device, wherein the instruction message is used for instructing the first terminal device to monitor a paging message of a second terminal device at a paging occasion of the second terminal device, or instructing the first terminal device to monitor a paging message of the second terminal device at a paging occasion of the first terminal device, the second terminal device communicating with the network device through the first terminal device: monitor the paging message of the second terminal device according to the instruction message.
 31. The terminal device according to claim 30, wherein the processor is further configured to execute the instructions to control the transceiver to send the paging message of the second terminal device to the second terminal device after the paging message of the second terminal device is monitored by the transceiver.
 32. The terminal device according to claim 30, wherein the paging message of the second terminal device is carried in a paging message of the first terminal device and the instruction message is a system message or a Radio Resource Control (RRC) dedicated signaling.
 33. (canceled)
 34. The terminal device according to claim
 30. wherein the processor is further configured to execute the instructions to control the transceiver to: send a state update message to the network device, wherein the state update message is used for updating link state information a link of between the first terminal device and the second terminal device.
 35. The terminal device according to claim 34, wherein the processor is further configured to execute the instructions to control the transceiver to: receive a response message for the state update message from the network device; monitor according to the response message, a paging message of the second terminal device at a paging occasion of the second terminal device or monitor a paging message of the second terminal device at a paging occasion of the first terminal device.
 36. The terminal device according to claim 35, wherein the processor is further configured to execute the instructions to control the transceiver to: monitor the paging message of the second terminal device at the paging occasion of the second terminal device in condition that the response message comprises a Radio Resource Control (RRC) connection release message and the RRC connection release message comprises a connection failure indication message; or monitor the paging message of the second terminal device at the paging occasion of the second terminal device in condition that the response message comprises an RRC connection rejection message; or monitor the paging message of the second terminal device at the paging occasion of the first terminal device in condition that the response message comprises an RRC connection reconfiguration message.
 37. The terminal device according to claim 36, wherein the processor is further configured to: in condition that the response message comprises the RRC connection release message or the RRC connection rejection message, determine that the state update message is not required to be resent to the network device in condition that the link between the first terminal device and the second terminal device is disconnected.
